Dapagliflozin reduces hospitalization risk in CKD patients regardless of diabetes status
Israel: SGLT2 inhibitor dapagliflozin may reduce the hospitalization risk due to any cause in patients with CKD (chronic kidney disease) irrespective of the presence or absence of type 2 diabetes, according to findings from a post hoc analysis of the DAPA-CKD trial. The study was featured in the Annals of Internal Medicine on Dec 6 2022.
Acute hospitalizations are frequent in CKD patients and often result in decreased health-related quality of life (HRQOL) and increased care costs. Meir Schechter, Hebrew University of Jerusalem, Jerusalem, Israel, and colleagues aimed to determine the impact of dapagliflozin on first and subsequent hospitalizations and all (first and subsequent) hospitalizations and investigate effects on cause-specific hospitalizations.
For this purpose, the researchers conducted a post hoc analysis of a DAPA-CKD, a double-blind, randomized, placebo-controlled clinical trial. The study was conducted across 386 ambulatory practice sites in 21 countries from Feb 2 2017, through Jun 12 2020. The study included adults with an eGFR (estimated glomerular filtration rate) of 25 to 75 mL/min/1.73 m2 and a urinary albumin–creatinine ratio (UACR) of 200 to 5000 mg/g, with and without type 2 diabetes (T2D). They were randomized in a ratio of 1:1 to receive 10 mg once daily dapagliflozin or a matching placebo.
The authors determined the effects of dapagliflozin on all hospitalizations, first hospitalizations for any cause, and cause-specific (first and recurrent) hospitalizations. Reasons for admission were evaluated using the reported system organ class. Hospitalizations were assessed using the Lin–Wei–Yang–Ying method for all hospitalizations or death, Cox proportional hazards regression models for first hospitalization and negative binomial models for cause-specific hospitalizations.
The authors reported the following findings:
- The study included 4304 patients (mean age, 61.8 years; 33.1% women).
- During a median follow-up of 2.4 years, 2072 hospitalizations were reported among 28.4% of participants.
- Compared with placebo, dapagliflozin reduced the risk of a first hospitalization (hazard ratio, 0.84) and all hospitalizations or death (rate ratio, 0.79).
- The authors did not observe any evidence that dapagliflozin effects on first and all hospitalizations varied by baseline presence of type 2 diabetes.
- Dapagliflozin, compared to placebo, reduced the admissions rate due to renal and urinary disorders, cardiac disorders, metabolism and nutrition disorders, and neoplasms.
"These results underscore additional benefits of dapagliflozin beyond those seen for kidney and cardiovascular events, all-cause and cause-specific mortality, eGFR slope and albuminuria and should be considered for evaluating the totality of evidence favouring provision of dapagliflozin to CKD patients," the researchers wrote.
To conclude, dapagliflozin reduced hospitalization risk for any cause in CKD patients regardless of diabetes patients.
